# tensorflow::ops::MatrixDiag

`#include <array_ops.h>`

Returns a batched diagonal tensor with a given batched diagonal values.

## Summary

Given a `diagonal`, this operation returns a tensor with the `diagonal` and everything else padded with zeros. The diagonal is computed as follows:

Assume `diagonal` has `k` dimensions `[I, J, K, ..., N]`, then the output is a tensor of rank `k+1` with dimensions \[I, J, K, ..., N, N\]\` where:

`output[i, j, k, ..., m, n] = 1{m=n} * diagonal[i, j, k, ..., n]`.

For example:


```
# 'diagonal' is [[1, 2, 3, 4], [5, 6, 7, 8]]
```

<br />


```
and diagonal.shape = (2, 4)
```

<br />


```
tf.matrix_diag(diagonal) ==> [[[1, 0, 0, 0]
                                     [0, 2, 0, 0]
                                     [0, 0, 3, 0]
                                     [0, 0, 0, 4]],
                                    [[5, 0, 0, 0]
                                     [0, 6, 0, 0]
                                     [0, 0, 7, 0]
                                     [0, 0, 0, 8]]]
```

<br />


```
which has shape (2, 4, 4)
```

Arguments:

- scope: A [Scope](https://www.tensorflow.org/versions/r1.15/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object
- diagonal: Rank `k`, where `k >= 1`.

<br />

Returns:

- `https://www.tensorflow.org/versions/r1.15/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output`: Rank `k+1`, with `output.shape = diagonal.shape + [diagonal.shape[-1]]`.
